In an excerpt from new ebook Robert Pattinson, Kristen Stewart, Taylor Lautner - In Their Own Words, Stewart is quoted as saying: "Nowadays it's harder because everyone is on Facebook and everyone knows where you are all the time, and everyone's Twittering.

"I'm going to die because somebody is going to say where I am and somebody is going to kill me. Someone's going to Twitter my location and it's going to be, like, boom."
